Visco ,   et al. | April 10, 2001 |
A method for fabricating an active metal electrode involves depositing lithium or other active metal electrode on a protective layer. The protective layer is a glassy or amorphous material that conducts ions of the active metal. It may be deposited on a releasable web carrier or other substrate such as polymer electrolyte layer. Lithium is then deposited on the protective layer. Finally, a current collector is attached to the lithium.
